ActiveX documents are similar to the forms you use to create VB applications. You can add controls, manipulate properties, invoke methods, and add code to events in an ActiveX document just as you would a form. They can be packaged in either in-process or out-of process components. ActiveX documents integrate into container applications, such as Internet Explorer (version 3 or higher), Microsoft Binder, and VB (version 5 or higher). Such applications can open ActiveX documents and access its data files.
